I had asked a question on Math SE, before I knew about Puzzling SE. Here's the link.


It does involve some maths, but it could be considered more of a puzzle. Please let me know where it is more appropriate; I'll delete the other version to avoid duplicates.

    $\begingroup$ I am surprised that it didn't get a great answer on Math.SE! There are so many people there who are excellent with game theory, strategy, and these types of questions in general. I think it could go either place. $\endgroup$

    $\begingroup$ I think this question should be simplified at first. For one, having both player's skills randomly be between $0$ and $1$ will require integrating a (probably complicated) function over a square. Also, for even mildly complicated point systems, verifying the "90% of matches between 1000 and 1500 points" condition seems quite hard to check. Basically, this question seems pretty intractable as it stands, and narrowing down the search space would make it easier to get the ball rolling. $\endgroup$ May 10, 2015 at 20:47

    $\begingroup$ For me, the 90% between 1000 and 1500 condition was sufficiently arbitrary to turn what might otherwise be an interesting question into a probably-unanswerable mess. $\endgroup$

  • $\begingroup$ @JLee Where should I delete it from? $\endgroup$ May 11, 2015 at 9:27
  • $\begingroup$ @ghosts_in_the_code You decide. Either is fine. Maybe just leave it like you have it now, with the question there, and the link to it here, and whichever site it is answered on, then delete it from the other place. However, MikeEarnest hit the nail on the head. $\endgroup$

  • $\begingroup$ If you're going to leave this question on puzzling.SE, I suggest stating the entire question here (in addition to the link). $\endgroup$ May 11, 2015 at 14:55
  • $\begingroup$ @Julian and others, Please tell me where to retain the Q and where to delete it. I'm fine with it either way, I just want to know which is better. $\endgroup$ May 11, 2015 at 16:17
  • $\begingroup$ In edge cases like this, the advice I've seen with other sites is: pick the site where you think you'll get the best response. $\endgroup$

1 Answer 1


Until a solution is posted, it's hard for us to say.

The difference between a maths puzzle (suited for Puzzling.SE) and a maths problem (suited for Maths.SE) depends essentially on the way it needs to be solved - see here. The criteria for a maths puzzle listed in the accepted answer there are:

  • Clever or elegant solution, often an "aha" moment.
  • Unexpected problem statement.
  • Unexpected or counterintuitive result.

That answer goes into a lot more detail about the distinction, but there's the essence of it.

  • $\begingroup$ Then I'll just leave it on Math SE. There may not be a good solution to it. $\endgroup$ May 12, 2015 at 9:12
  • $\begingroup$ @ghosts_in_the_code There you go. $\endgroup$
